This document provides a case study about a partnership between an insurance company (IFA) and grocery chain (ShopSense) to share customer data. IFA's regional manager Laura Brickman wants to buy ShopSense's customer loyalty card data to identify correlations between purchases and medical claims. While this could provide business value, executives at both companies have concerns about customer privacy and reaction if they found their data was being shared. The case aims to discuss how companies can responsibly use shared customer data to avoid damaging customer trust and relationships.
